Isono ,   et al. | April 30, 1991 |
Two recording tracks (T1) and (T2) are formed in parallel with each other on a stereoscopic video disc record (D). Image information for a right eye and audio information are serially recorded on one recording track (T1). Image information for a left eye and audio information are serially recorded on the recording track (T2) at a synchronized timing with the image information for a right eye and the audio information recorded on the adjacent recording track T1. Information can be easily recorded on such steroscopic video disc record (D) in a manner that the image information for right and left eyes and the audio information are recorded at the same time by two recording beams. On the other hand, stereoscopic image information can be reproduced by reproducing respective recording tracks at the same time by two reproducing means. Furthermore, a normal two dimensional image information can be reproduced by reproducing either one of the recording tracks serially by one reproducing beam.
